WILLIAM H. SLAYBAUGI-I, OF EAST TOLEDO, OHIO, ASSIGNOR OF THREE-EIGHTHSTO WILLIAM T. DAVIES, 0F TOLEDO, OHIO.

DRIER FOR GRAIN OR THE LIKE.

To all whom it may concern:

Be it known that I, VILLIAM H. SLAY- BAUGH, a citizen of the UnitedStates, and a resident of East Toledo, in the county of Lucas and Stateof Ohio, have invented a certain new and useful Drier for Grain or theLike; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make Aand use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

My invention relates to driers for grain, corn or the like, but is notrestricted to such use as it can be used in any connection for which itmay be appropriate as for screening purposes or the like.

The object of my invention is the provision of an improved apparatus ofthis class, which is simple and eiiicient in its construction,economical of manufacture, and capable of being easily and quickly setup or knocked down, whereby to enhance its practicability and commercialvalue.

The invent-ion is fully described in the following specification, andwhile in its broader aspect it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawings, in which,-

Figure 1 is a central vertical section of the apparatus embodying theinvention. Fig. 2 is an enlarged section on the line m in Fig. 1. Fig. 3is a side elevation of the machine. Fig. 4 is a cross-section on theline g/ y in Fig. 3, with al portion broken away, and Fig. 5 is a topplan view thereof.

Referring to the drawings, 1 designates the housing or casing of anapparatus comprising my invention, and is shown, in the presentinstance, as comprising a plurality of rectangular sections, preferablyof sheetmetal, which are placed edge to edge one over the other to buildthe apparatus to any desired height, the abutting edges of the sectionsbeing secured together by bands 2 which are bolted to the associatededges of the sections which they lap. This provides a housing structurewhich can be easily built up or knocked down, as desired.

Located within the housing 2 in superimposed order are a plurality ofshaker-frames specification of Letters Patent.

3, which have their bottoms adapted for the passage of air therethrough,being screened, perforated or otherwise suitably formed for suchpurpose. Alternate ones of the shakerframes 3 are oppositely inclined,as indicated, and the elevated end of each frameprojects beyond theadjacent or lower end of the frame next above to adapt it to catchmatter falling therefrom. It is thus apparent that matter will pass inone direction down one frame, from which it falls to the elevated end ofthe frame next below and passes down it in the opposite direction, andso on to the bottom of the apparatus. The elevated end of each frame,except in the present instance the top one, is provided with an upwardlyand outwardly project-ing flange 4 which is carried by the frame andcontinually held in contact with the adjacent side of the housing 1during a reciprocatory or shaking movement of the associated frame byspring fingers 5, as shown, thus preventing matter falling from oneframe to another from passing between the housing side and t-he elevatedend of a frame.

Each frame 3 is suspended at the sides thereof from bars 6 by pivotallinks 7 which connect the bars and frame adjacent their ends. The bars 6are preferably of angle iron, as best shown in Fig. 2, and have theirhorizontal flanges projecting inwardly from the housing sides andresting upon the downwardly and inwardly turned ends of fulcrum pins 8which project from t-he adjacent housing sides centrally of the bars 6.The frames are arranged and operated in pairs and between the spacedends of each pair transversely thereof are located the rock-shafts 9 and10, which are suitably journaled in the housing sides and project at oneend without such sides, as shown in Fig. 3. The shaft 9 carries avertically disposed cross-arm 11, the opposite ends of which areconnected by links 12, 12 to the adjacent ends of the associated bars 6,as best shown in Fig. 1, thus adapting a rocking of the shaft 9 toeffect a vertical rocking of the bars 6 and attached frames 3 toward andaway from each other. The rock-shaft 10 has vertically disposedcross-arms 111 mounted thereon adjacent the housing sides, the ends ofwhich are connected by links 15, 15 to the respective upper and lowerframes 3 of the associated set adjacent their centers, as indicated,thus causing a rocking of the shafts 10 to impart a longitudinalreciprocatory movement to each of the at- 5 tached frames 3. Theconnecting of the rock-shafts to the frames 3 and bars 6 in this mannercauses them to Yhave vertical oscillatory movements toward and away fromleach other and simultaneous horizontal shaking or reciprocatorymovements in reverse directions, thus creating a balanced action toeliminate jar from the apparatus.

i The shafts 10 are provided Withoutone side of the housing 1 withhorizontallyprojecting crank-arms 16, which are all connected togetherby a vertical bar 17 having pins 18 working in horizontal slots 19 inthe arm ends, as shown in Fig. 3. The bar 17 also attaches to the outerends of rock- 20 arms 2O projecting horizontally from the stud 24projecting from the housing side.

The horizontal arm of the lever 23 is connected by a bar 25 'to aneccentric strap 2G which is mounted on an eccentric 27 carried byv ashaft 28 on top of the housing 1. The shaft 28 is shown, in the presentinstance, as carrying a stepped pulley 29 which is connected 'by a belt3() to a stepped pulley 31 on a shaft 32 mounted on the top of the 35housing adjacent one side thereof. The shaft 32 carries a drive pulley33 which may be driven in any suit-able manner. It is apparent .that allof the rock-shafts 9 and 10 are operated in unison froml a singleeccentric 27 and that such eccentric may be driven at any desiredV speedby changing the belt on the stepped pulleys 29 and 31.

Grain or other matter is delivered to the elevated end of the uppershaker frame 3 through a hopper 34 into which it may be deposited by achute 35 or in any other suitable manner.

Located within the apparatus between the shaker frames 3 are a pluralityof sets of steam coils 36 which are shown as connecting with Veach otherwithout the sides of the housing 1 by pipes 37 and the lower one ashaving Vconnection with a supply pipe 38. The purpose of the steam pipes36 is to heatair passing through the apparatus to facilitate a drying ofmatter in its passage over the shakers 3.

A circulation is created within the housing 1 by a fan 39 which iscarried within a conduit or casing 40 at the top of the housing by ashaft 41. The fan is driven by a i belt 42 connect-ing the pulley 43 onits shaft with the pulley 44 on the shaft 32. (See Fig. 5.) The conduit40 has communication with the interior of the housing through the topthereof and upon a rotation of the fan, air is caused to enter thehousing through openings 45 at the lower end thereof and pass upwardlythrough the housing and perforated bottoms of the frames 3, being heatedby radiant heat from the steam pipes 36 as it ascends, and leaves thehousing through the conduit 40.

Grain or other matter, after leaving the lower shaker frame 3, dropsupon an inclined trough 4G by which it is delivered from the housingthrough an opening 47 in one side thereof.

48 designates angle-iron bars which are secured vertically to the sidesof the housing and serve to strengthen such sides, unite the sectionsthereof, and to hold the fulcrum pins 8 supporting the bars 6.

In the operation of my improved apparatus, grain, corn or other matterto be dried is deposited in the hopper 34 by which it is delivered tothe upper shaker frame 3. The matter traverses the length of thesuccessive frames, falling from one to the other in its progress andfinally being delivered in a dried state from the apparatus by thedelivery trough 4G. The matter is agitated and its progress over therespective frames 3 facilitated by the compound vertical oscillatory andhorizontal reciprocatory shaking movements which are communicated to theframes 3 by their connection with the rockshafts 9 and 10, which are inturn rocked by suitable connection with the eccentric 27, as abovedescribed. As the grain or other matter when in a wet or damp state ismore. sluggish in its movements and therefore does noty move as readilyas when in a drystate, each frame 3 is preferably inclined slightly morethan the one next below, as shown in Fig. 1. As the grain passesdownwardly across the shaker frames and from one to another thereof, thehot air passing upwardly through the interior of the housing and theperforated bottoms of the frames causes the matter to be thoroughlydried before leaving the housing. lVhile only four shaker frames areshown, it is apparent that any desired number of the same may be used.

I wish it understood that my invention is not limited to any specificconstruction or arrangement of the parts except in so far as suchlimitations yare specified in the claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is,
